Penetrant Testing (PT) (2)
Penetrant Testing (PT) is a powerful method for detecting surface-breaking discontinuities and through-thickness leak paths in nonporous materials and is one of the basic NDT methods with numerous applications in the industry. Test indication visibility is governed by contrast against its surroundings, so inspections must be performed under proper lighting conditions Indications of flaws can be found regardless of the size, configuration, internal structure, or chemical composition of work piece being tested and regardless of flaw orientation.
